How to move an iMac 2,800 miles

I've got a 20" PPC G5 iMac, and I'm going to be moving from the SF Bay Area to Baltimore during this summer. Does anyone know of a good way to transport the iMac across the country? If it were up to me, I'd either hand carry it on the plane or dump it for a new Al iMac in Baltimore, but I think it's way too large in a box to hand carry it and I don't have sufficient funds for a new iMac.

As a side question, does anyone know of some good RAM that I can upgrade this thing to? It's currently running off of 512 megs, and I'd like to bump that up to 2 gigs so Leopard can run smoother.
